  • The objective of this study is to present and to analyze preliminary orientation design factors in the design stage of sustainable architecture in the viewpoint of technocentrism. Typically people interpret solar energy system architecture as simply being part of a mechanical system. Yet, even before considering energy-consuming physical systems in buildings, it is very important to consider the outer parameters of sustainable design factors and the design process itself for the effective and suitable energy-saving design methodology. By analyzing the evolving phases and history of technocentrism and solar energy systems in sustainable architecture through examples and case studies, this paper focuses on and proposes preliminary orientation design factors that should be considered when starting the architectural design process in the viewpoint of technocentrism.

  • In this study, Microstructure and hardness of 1st layer with crystallographic orientation were investigated about solidification structure in multipass weld using high Mn-Ni flux cored wire. Microstructure of solidification consisted of austenite matrix and a little ${\varepsilon}-phase$ in grain boundaries. Orientation of grains was usually (001), (101), (111). According to crystallographic orientation, morphology of primary dendrite was different. The depletion of Fe and the segregation of Mn, C, Ni, Si, Cu, Cr, O were found along the grain boundaries. The area of segregation was wide with an order of (001), (101), (111) grains. And hardness of grains with crystallographic orientation increased with an order of (001), (101), (111) grains because of the segregation along dendrite boundary.

  • This study was administered to identify features of masstiege high-end products by comparing to original old high-end products. For this purpose, the differences in shopping orientation between each consumer groups by product types(high-end products, original old high-end products) preferred were examined. 300 female consumers were surveyed and 279 data were used for analysis. The results are as follows. First, three elements(efficiency, enjoyment, convenience) of shopping orientation were constructed by factor analysis and efficiency element of all elements had highest explanation power. The differences in shopping orientation between masstiege high-end products and original old high-end products were identified by t-test. The consumers preferring original old high-end products regarded convenience element as an important factor and the consumers preferring masstiege high-end products considered efficiency element more. The correlation analysis between shopping orientation factors and demographic characteristics were administered. The consumers who were of low age, low education, low income and unmarried pursued efficiency more, the consumers who were unmarried, of high education and high income showed to pursue enjoyment more, and the consumers who were of high age, high education, high income and married considered convenience element more. Finally marketing strategies for masstiege brands were suggested.

  • This paper presents an automatic fixture planning system for machining processes of prismatic parts. A rationalized approach to integrate fixture planning with process planning is proposed and representation schemes for workpiece, part design information with features, machine tools, cutting tools and fixtures are developed. The proposed system implements two activities of fixture planning such as machining of reference surfaces and machining of features. For machining of reference surfaces, the machining sequence of reference surfaces is determined by using decision tables, which are drawn from relations of part dimension, degree of surface roughness, fixture type and its capacity, cutting tool's capacity and experienced planners' knowledge. For machining of features, a preferential machining orientation is selected for its feature which can be machined in more than one direction, and features with the same machining orientation are grouped, and the machining sequence of features is determined by interactive mode. A case study is performed to show the performance of the proposed system.

  • The properties of FRP usually depends on the fabricating method. The fiber orientation of FRP is also depends on the fabricating method. The fiber orientation in FRP has a great effect on the strength of FRP because the strength of FRP mainly depends on the strength of fiber. In this study. compressive and bending strength of FRP rods were investigated. Inner part of FRP was made unidirectionally by pultrusion method and outer part of FRP was made by wrapping method. The size effect was also investigated with pultruded FRP rods.

  • Recently, the role of IT service providers has been enlarged from managing a single function or system to reconstructing entire information management processes in new ways to contribute to shareholder value across the enterprise. This movement toward extensive and complex outsourcing agreements has been driven by the assumption that outsourcing information technology functions is a reliable approach to maximizing resource productivity. Hiring external IT service providers to manage part or all of its information-related services helps a firm focus on its core business and provides better services to its clients, thus obtaining sustainable competitive advantage. This practice of focusing on the strategic aspect of outsourcing is referred to as strategic sourcing where the focus is capability sourcing, not procurement. Given the importance of the strategic outsourcing, however, to our knowledge, there is little empirical research on the relationship between the strategic outsourcing orientation and outsourcing performance. Moreover, there is little research on the factor that makes the strategic outsourcing effective. This study is designed to investigate the relationship between strategic IT outsourcing orientation and IT outsourcing performance and the process through which strategic IT outsourcing orientation influences outsourcing performance, Based on the framework of strategic orientation-performance and core competence based management, this study first identifies core competency orientation as a proper strategic orientation pertinent to IT outsourcing and IT outsourcing process management capability as the mediator to affect IT outsourcing performance. The proposed research model is then tested with a sample of 200 firms. The findings of this study may contribute to the literature in two ways. First, it draws on the strategic orientation - performance framework in developing its research model so that it can provide a new perspective to the well studied phenomena. This perspective allows practitioners and researchers to look at outsourcing from an angle that emphasizes the strategic decision making to outsource its IT functions. Second, by separating the concept of strategic orientation and outsourcing process management capability, this study provides practices with insight into how the strategic orientation can work effectively to achieve an expected result. In addition, the current study provides a basis for future studies that examine the factors affecting IT outsourcing performance with more controllable factors such as IT outsourcing process management capability rather than external hard-to-control factors including trust and relationship management. This study investigates the major factors that determine IT outsourcing success. Based on strategic orientation and core competency theories, we develop the proposed research model to investigate the relationship between core competency orientation and IT outsourcing performance and the mediating role of IT outsourcing process management capability on IT outsourcing performance. The model consists of two independent variables (core-competency-orientation and IT outsourcing process management capability), and two dependent variables (outsourced task complexity and IT outsourcing performance). Comprehensive data collection was conducted through an outsourcing association. The survey data were analyzed using a structural analysis method. IT outsourcing process management capability was found to mediate the effect of core competency orientation on both outsourced task complexity and IT outsourcing performance. Further analysis and findings are discussed.

  • Injection molding is the most widely used process for the industrial forming of plastic articles. During an injection molding process of composites, the fiber-matrix separation and fiber orientation are caused by the flow of molten polymer/fiber mixture. As a result, the product tends to be nonhomogeneous and anisotropic. Hence, it is very important to clarify the relations between separation·orientation and infection molding conditions. So far, there is no research on the measurement of fiber orientation using image processing. In this study, the effects of fiber content ratio and molding condition on the fiber orientation-angle distributions are studied experimentally. Using the image processing method, the fiber orientation distribution of welding parts in injection-molded products is assessed. And the effects of fiber content and injection mold shapes on the fiber orientation in case of fiber reinforced polymeric composites are studied. experimentally.

  • 본 연구는 국제물류주선업체의 부서 간 역학관계가 시장지향성에 어떠한 영향을 미치는지, 그리고 시장지향성이 관계몰입을 통해 고객성과에 미치는 영향에 대해 규명하여 국제물류주선업체의 경쟁력을 향상시키고자 실시하였다. 연구결과 부서 간 연계를 통해 부서 간 갈등수준이 낮아져야 시장지향성이 높아진다는 것을 알 수 있었다. 하지만 시장지향성이 고객성과에 미치는 영향에 대해서는 유의한 영향력을 확인할 수 없었으며, 시장지향성은 관계몰입이라는 매개변수를 통해 고객성과에 유의한 영향을 미친다는 점이 밝혀졌다. 현재 우리나라의 국제물류주선업의 시장은 매우 경쟁적이며, 경쟁전략의 대부분이 비용전략이며, 비용전략은 다른 경쟁기업이 고객에게 제공하는 비용에 따라 수시로 바뀌는 실정임을 비추어 볼 때, 국제물류주선업체들은 출혈경쟁을 지양하고, 고객기업과의 신뢰형성과 장기적인 관계유지를 위해 노력을 기울여야 경쟁력이 강화될 것으로 보인다.
